That's fine, but you're implicitly agreeing that you're okay with my
innocent Math.max() assignment changing the implementation from a
value-copy to a heap-store, along with the potential performance
implications. I believe that's what triggered this thread in the first
place. I think Alex Blewitt was saying that the "final" keyword forces
one implementation over another, and it's therefore a useful
indicator.

Also, the paragraph you responded to was not about writable access to
free variables from lambdas, but about CICE-style effective-final
changes to anonymous inner classes. That's what we have no experience
with.
